The present invention relates, generally, to a tool for applying molten wax for purposes such, for example, as making batik work; and the invention relates, more particularly, to a tool'for holding a quantity of wax, for melting it, and for feeding the molten wax as desired.

An object of, the invention is to provide a wax holder having a feeding spout and an electric heater for the holder to melt the wax fed to the spout.

Another object of the invention is to provide a contractible chamber for forcing molten wax to an applying element and withdrawing it therefrom.

Various other objects and advantages of the invention will be obvious from the following particular' description of a form of apparatus embodying the invention or from an inspection of the accompanying drawings; and the invention also consists in certain new and useful features of construction and combinations of parts hereinafter set forth and claimed.

In the. accompanying drawings there is shown for purposes of illustration one form of apparatusembodying the invention, in which:

Fig. 1 is an elevation view;

Fig. 2 is a vertical section view, in part, with closure parts moved to open position;

Fig. 3 is a section View taken along the line 33 of Figure 2, looking in the direction of the arrows;

Fig. 4 is an elevation view in detail of the apparatus;

,- Figs. 5 and 6 are, respectively, front and right side vertical elevation views with the closure parts in closed position; and

Fig. 7 is a vertical section view, in part, of an alternate embodiment.

In all the above described views like charact-ers of reference are used to indicate corresponding parts throughout.

Referring now to the drawings the reference character 1 indicates a barrel having an annular cap lat the top end and an annular cap 3 screwed onto the lower end. In the lowerend'of cap 3 is screwed a feed spout 4t which its letter end has zit-removable tip S part of a 1928. Seria1 No. 284,687.

and at its upper end has a threaded counter bore 6. Into said counter bore 6 isthreaded the boss formed on the block 8 positioned within said barrel 1 and having formed therethrough a bore 9 which connects, through said boss 7 ,to the bores of said spout 4 and its tip 5, the upper face of said cylinder 8 bein made concave to form a guide for molten wax to flow to said bore 9.

In said block 8, transverse to and connecting with said bore 9 intermediate the latters length, is formed a bore 10 greater in diameter than bore 9 and having one end closed. Movable longitudinally in said bore 10 is a'piston 11 having a piston ring 12 (shown in section) positioned in an annular groove thereon to make close fit with the wall of said bore 10. On an axially aligned stud 13 extending from its inner end, said piston 11 carries a closure member 14 for that part 9 of bore 9' which is above said bore 10, said stud 13 serving to space apart said closure member 14' and piston 11 to provide a passageway between them for the flow of wax when said closure member His moved inwardly from a position across said bore 9' to bring said stud 13 adjacent thereto. Said closure member 14 is cylindrical in shape with sliding fit in said bore 10 and has a sector removed for its entire length below its horizontal diameterto define a space between it and the lower side of said bore 10. The inner end of said bore 10 serves as a stop for said closure 14 and piston 10 on inward movement and a countersink 15 at the inner end of said bore 10 provides a space which connects with the space below said closure member 14. A leaf spring 16, mounted at one end to the inside wall of said cylinder land at its other end to the outer end of said piston 11, serves to hold said piston 11 and closure member 14 in a position in which the latter is positioned across and closes the lower end of said bore 9'. It is to be particularly noted that when said spring 16 is pressed in said piston 11 starts moving inwardly in said bore 10 before said bore 9 has begun to be opened; and, also, that when spring 16 is released said piston. 11 will'be moving outwardly inbore 10 after closure 14 has completely closed bore 9 and that, during this movement, bore 9 will be kept closed while piston 11 is still moving outwardly.

Said block 8 serves as the bottom closure of a wax holding tube 17 which extends upwardly through said barrel 1 and through the central opening of said annular cap 2 above which latter said tube has a cap closure 18. About said tube 17 and electrically insulated therefrom is a coil of heater wire 19 which has two terminals 20, 20 mounted to the outside of and insulated from said barrel 1, and adapted to connect leads 21, 21 to said heater wire 19. A knob 22 attached to said spring 16 and extending out through an openin 23 in said barrel 1 serves for movin sai closure 14 against the pressure of sai spring 16 topermit passage of molten .wax 24 from said tubel7.

In the use and operation of the above described apparatus of the invention as, for

example, to make batik designs, a body of wax 24 is supplied to said tube 17 and melted or kept melted therein b heat supplied from said heating coil 19. en said wax 24 is at a proper state of fluidity it is fed to and through said spout 4 by pressing said knob 22 1n, against said spring 16, to move said closure member 14 from its normally closed position across the lower end of said bore 9 (see Figs. 1, 2 and 3), whereupon said wax will flow out through the tip 50f spout 4 onto a fabric or other material to-which the wax is to be applied, said tip 5 being used to press the molten wax into the fabric. and to spread it in the configuration or design desired.

To stop the flow of wax the knob 22 is released to ermit spring 16 to draw said closure 14 ack into position across the lower end of saidbore 9. During this return movement'the suction caused by the displacement of said piston 11. from said bore 10 willcause the, wax in said bore 9 to be drawn back into said bore 10 and into the upper part of bore 9 and hold it there V It is to be noted particularly that there is a substantial'outward movement of piston 11 in bore 10, after bore, 9" has been closed by said clo'suref14, which latter is 10 enough to keep said bored). closed until. t 's outward movement has ceased. This proyides that wax is prevented from flowing from'tube 17 while suckinguppf wax from bore 9 is onti ue In this positionpfp r fi h t transntitted-, froni said heater 19, through intepadi -cent -metal parts, will maintain the wax-lathe molten state (see Fig. 5),

aridzcloggirig of the bore .of saidtip 5 by con eale wax will be avoided.

; h on next the knob 22 is pressed in to meiemideiese e 4 to, pe said bo to again feed wax said piston 11, on its inward movement, will displace the wax out of said bore 10 and push it out into said bore 9 so that by the time said bore 9 is opened the molten wax will again be at the feeding tip 5. During the commencement of the inward movement of said piston 11 in bore 10 said closure 14 will be in com letely closing relation across said bore 9 so that downward movement of wax in bore9 by piston 11 is begun before said bore 9 is opened.

In Figure 7 is illustrated an alternate embodiment of the invention in which is the block 25 mounted at the lower end of a wax holdin c linder 17 and having an axially aligne therefrom. In said boss 26 is formed a bore 27 which extends upwardly and terminates in said block 25 where it connects with the side of a bore 28 which extends inwardl from one side of said block 25 and termioss 26 extending downwardly nates therein at a point beyond the end of i said bore 27. A bore 29 extending downwardly from'the upper surface of sald block 25 connects with the end of said here 28 through a bore 30 which is axially ali d with and smaller in diameter than said ore 28. Mounted in said bore 28 is a piston 31 having its inner end conical in shape to adapt it to seat against the inner end of bore 28 and to close said here 30. A spring 32 attachedat one end to the outer end of said piston 31 and at its other end to the inner surface of a cylinder. 1 enclosing cylinder 17 normally holds said piston 31in the unseated position so that normally there is an unobstructed passage from bore 29, through bores 30 and 28, to said bore 27. A thumb knob 33 mounted to said spring 32 and extending through an opening 84 in said cylin- 4 der l'serves to move iston 31 into seating.

position to close said ore 30, and a piston r ring 35 mounted in an annular groove about said piston 31 serves to prevent leakage of molten wax thereby.

On said boss 26 is mounted, in threaded i. relatioma feed spout 36 which has a 0011i: cal counter bore 37 at its upper end which carries a ball 38 which, by turning up said spout 36, can be seated against the lower end" of said'bore' 27 to close it and in the same way can be adjusted in its distance from the end of said bore 27 tocontrol the rate of flow of wax through the spout.

channels .in'the sidesof said bore 37 provide"? passagewayfor waxupast said ball 38;

In sziid'bbre' 29 is :provided a) tube which. at its lower end'has a counter emf 41 in which is provided'a b31142 adaptedto seat against the upper end of said counter,"

*bore 41 and close the main bore 43 of tube 1' 40. Fingers 44 formed on the lower end of, said tube hold saidlball 42 in tube 4o Fluted F I and. have spaces the'rebet'ween to permit passage of-molten wax thereby.

' In the use and operation of this embodiment of my invention the tool is normally open to'permit the flow of molten wax therefrom, the piston 31 being adapted, by pressing knob 33, to be moved by the hand of the manipulator of the tool to close said bore to stop the flow of wax when the tool is moved from one part to another of the material being decorated or for stopping flow until thetool can be inverted into a position in which gravity keeps the molten wax from flowing out; As'above noted the spout 36 ean he turned on its threads on boss 26 to regulate the rate of flow ofthe wax from thetool. i V

fBy quickly moving piston 31 inwardly said ball 42can be forced against the end of bore 43 to close it and molten wax forced under pressure from spout 36 either to force itinto the material being decorated or to clearflthebor'e of spout 36 of congealed wax. ilVhile I have shown and described and nav'e oinaa out in the annexed claims oer tain novel features of the invention, it will be'underst'ood that various omissions, substitutions an'd changes inthe'torms and details ofthe devices illustrated and in its use and goop'eration may be made by those skilled in the art without departin from the spirit oi the invention;
